Summary
On certain subject vehicles, it is possible that the panic alarm system may activate while driving, and the horn may sound intermittently and hazard warning lights may flash. The panic alarm concern will stop after cycling the ignition switch off, then on again. No DTCs are stored. Some TPMS wheel sensor IDs on the concerned vehicle or other vehicles nearby may cause the error in the body control module (BCM). Air pressure data transmitted from the wheel sensors may be recognized by the BCM as if the panic button on the remote transmitter has been pressed.
